We construct a narrative instrument for government investment from official records in Germany. Using structural vector autoregressions, we document a significant crowding-in of private investment and an output multiplier of roughly 2. Then, we match a New Keynesian dynamic stochastic general equilibrium model to the empirical responses, and we decompose the multiplier into three channels. Public investment ...

Using a data-driven approach to identify structural vector autoregressive models, we examine key factors influencing the US dollar exchange rate across eight advanced economies from 1980 to 2022. We find that shocks to inflation expectations, which are closely tied to unfunded government transfer payments, have a pronounced effect on the US dollar’s value. This underscores the fiscal dimension of exchange ...

Theory suggests that corporate and sovereign bonds are fundamentally different, also because sovereign debt has no bankruptcy mechanism and is hard to enforce. We show empirically that the two assets are more similar than you think, at least when it comes to high-yield bonds over the past 20 years. Based on rich new data we compare risky US corporate bonds (“junk” bonds) to risky emerging market sovereign ...

Urban areas confront a chronic shortage of housing, especially in the low-rent segment. This precarious situation is further exacerbated by major challenges, like the destruction of housing by wars and natural catastrophes, rapid increase of demand, or pandemics cutting incomes. In response, the authorities implement rent control that slows rent increases or even freezes rents. Rent control is ubiquitous, ...

This paper first shows that, contrary to conventional wisdom, the European Central Bank (ECB) can influence global energy prices. Second, through Lucas critique-robust counterfactual analysis, we uncover that the ECB’s ability to affect fast-moving energy prices plays an important role in the transmission of monetary policy. Third, we empirically document that, to optimally fulfill its primary mandate, ...

Abtract englischExploiting the heteroscedasticity of the changes in short-term and long-term interest rates and exchange rates around the FOMC announcement, we identify three structural monetary policy shocks. We eliminate the predictable part of the shocks and study their effects on financial variables and macro variables. The first shock resembles a conventional monetary policy shock, and the second ...

Business cycle models often abstract from persistent household heterogeneity, despite its potentially significant implications for macroeconomic fluctuations and policy. We show empirically that the likelihood of being persistently financially constrained decreases with cognitive skills and increases with overconfidence thereon. Guided by this and other micro evidence, we add persistent heterogeneity ...

The low degree of stock market participation (SMP) is one of the big puzzles in finance. Numerous determinants have been proposed. We put these determinants into a structure that is derived from a standard static portfolio model. Then we discuss arguments put forward regarding specific SMP determinants and the empirical evidence that has been provided. The focus of our survey is on the identification ...

Financial repression lowers the return on government debt and contributes, all else equal, towards its liquidation. However, its full effect on the debt-to-GDP ratio hinges on how repression impacts the economy at large because it alters investment and saving decisions. We develop and estimate a New Keynesian model with financial repression. Based on U.S. data for the period 1948–1974, we find, consistent ...
